I very much doubt it's worth the fifty quid starting price, but I love stuff like this. This looks to me very like an old Classico brand guitar, just like the one I took lessons on when I was 11 (my sister still has mine at her house).
As to The Beano comic, well it was a British instituion. Absolutely fantastic! Don't accept any Dennis the Menace imposters with yellow hair, the real Dennis the Menace wore a red and black striped jersey, had black spiky hair and a dog called Gnasher.
